?? changing 12FV calibers ?? , 308 12fv accuracy?

[celltech]

Lets say, we had a factory stock .223 12FV, would that bolt face be smaller, and would be limited to the smaller dia. calibers that you listed?

I suggest you google bolt face diameters and do a little research. The .223 uses a .384" and is *not* compatible with any of the above listed rounds. But with a Savage you can easily swap bolt heads and barrels with the same action and create almost whatever you want.

How do you plan on threading the barrel for a brake? And yeah...you have lots of room to practice. I cut down my .308 to 18" with a hacksaw and crowned it with a shell deburring tool...still shoots 1/2" groups and lost a lot of weight in the process.
